1:首先下載Nlog.dll,通過網上直接download 或者nuget 下載dll都可以。http://nlog-project.org/download/ 然后把下載下來的Nlog.dll ,Nlog,extension.dll 加入項目reference.
2:配置WebConfig文件:
<configuration>
<configSections>
<section name="nlog" type="NLog.Config.ConfigSectionHandler, NLog"/>
</configSections>
<nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<targets>
<target xsi:type="File" name="f" fileName="${basedir}/APP_Data/logs/${shortdate}.log" layout="${longdate} ${uppercase:${level}} ${message}" />
</targets>
<rules>
<logger name="*" minlevel="Trace" writeTo="f" />
</rules>
</nlog>
</configuration>
3:寫入日志:
private static Logger logger = LogManager.GetCurrentClassLogger();
logger.Info("info 日志");
logger.Trace("Trace 日志");
logger.Error("Trace 日志");
